Stage 15 - PWR Radiator - Cooling her down.

Vivid Racing in its ever lasting quest to have the best and most efficient car has undoubtedly upgraded one of the most important and sometimes overlooked components. The Radiator. The stock radiator is very efficient. But we all know cooling equals power. The cooler the car runs the more power we see out of it. The only option for us that we use in all our cars is the PWR Radiator from Australia. The PWR is a direct fit for your 2002-2004 WRX and STI. It is a drop in fit and your stock fans bolt right up. The cap is recommended to be upgraded to a 1.3 bar cap to hold greater pressure. We chose the Monster Sport for this. The hoses were upgraded to Samco Sports silicon 2 piece kit in red to match the engine. The radiator was installed, fitted, and refilled with coolant from Redline, their Water Wetter. Now the car is efficiently cooled from the start and efficiency will increase.
